Function retryWithDelay

retryWithDelay<T>(f: Retryable<T>, doDelay: DelayFunction): Promise<T>
Retries an async function until it succeeds, using a delay function between attempts.
Type Parameters
- T
  The resolved return type.
Parameters
- f: Retryable<T>
  The function to retry.
- doDelay: DelayFunction
  Called after each failure. If it returns false, retries stop and null is returned.
Returns Promise<T>
The result of f, or null if retries were forfeited.
Throws
Propagates errors thrown or rejected by doDelay; errors from f are retried.

Remarks
f runs immediately with zero failures. After each rejection, doDelay receives the incremented failure count and latest error. Only an explicit false forfeits. Custom void-returning delays infer a nonnullable result. Boolean-returning delays, including every createExponentialBackoffDelay result, infer T | null.
Example
```
const result = await retryWithDelay(
    () => fetchData(),
    createExponentialBackoffDelay({ init_delay: 100, max_attempts: 3 }),
);
```
